Erratum

In the September 2002 issue of the Journal, in the report “Mutations in Two Genes Encoding Different Subunits of a Receptor Signaling Complex Result in an Identical Disease Phenotype,” by Paloneva et al. (71:656–662), the nucleotide of the Norwegian TREM2 mutation is incorrect. In the Norwegian family, a 558G→T mutation was found (not 558G→A, as was incorrectly presented in the report). The mutation results in conversion of lysine 186 to asparagine (K186N), and the conversion is correctly presented in the report. The authors apologize for the error.
